FWIW, that looks better to me.

I think that it would be okay to document that
shutil.ignore_patterns() only accepts patterns matching individual
filenames (not complex paths). If someone needs to do something with
absolute paths, then they can write their own 'ignore' function,
I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
